    Default how to pass a variable from a method to another

    in this code, i would like to know how to pass the convertedWorkArray from the first method to the second one ??
    1-both methods belong to the same class
    2-i dont want the method ( getsum) to receive any parameters from the (main), i just want to know how to set the (convertedworkarray) visible to the method (getsum)

    public  int []convertStrToInt() 
        		int [] convertedWorkArray = new int [workarray.length];
        		for (int i=0;i<workarray.length;i++)
        		    System.out.println("Your array was converted into integers");
                return convertedWorkArray;
     public int getSum()
         	int sum=0;
         	for (int i=0 ; i< convertedWorkArray.length ; i++)
         		sum+ = convertedWorkArray[i];
         		return sum;

    You need to give the getSum() method a parameter that accepts an int[]. Then you need to send it the int[] when you call the method:
    public int getSum(int[] arr)
            int sum=0;
            for (int i=0 ; i< arr.length ; i++)
                sum+ = arr[i];
                return sum;                    

    When asking for help, please follow these guidelines to receive better and more prompt help:
    1. Put your code in Java Tags. To do this, put [highlight=java] before your code and [/highlight] after your code.
    2. Give full details of errors and provide us with as much information about the situation as possible.
    3. Give us an example of what the output should look like when done correctly.
